I can definitely sympathise with your problem. We had the same for 3 or 4 years. All through the summer in the garden of a house behind us there were children playing but one of them used to scream at the top of their voice all the time. High, piercing and actually uncomfortable. Thankfully they moved!.
Other than a complaint to the council there's little you can do.
